Problems solved by technology

[0002] Cleaning staff often need to use manpower tricycles when cleaning the road. Manpower tricycles are very convenient to use on flat roads, and the speed is easy to control and not too fast. According to the structure of the tricycle, the angle between the steering kingpin and the vertical direction is the steering kingpin caster angle. If the steering kingpin caster angle is reduced, the steering is flexible, the riding is labor-saving, and it is suitable for uphill road conditions; Increase the caster angle of the steering kingpin, the handlebar will be more stable, and the riding will be strenuous, suitable for downhill road conditions

Abstract

The invention discloses a manpower three-wheeled cleaning vehicle with an adjustable caster angle of a steering main pin. The cleaning vehicle comprises a sleeve sleeving the steering main pin, a first connecting seat and a second connecting seat are arranged on the sleeve, a pin shaft is fixedly arranged on the first connecting seat, the front end of a vehicle beam is rotatably connected with thepin shaft, and a gear is fixedly arranged on the pin shaft; a locking device is mounted on the bicycle beam; the locking device comprises a locking seat, a locking pin and a locking spring, and the end of the locking pin is connected with a locking pull rope; an operation hand brake is installed on the bicycle beam, and a tensioning ring is further fixedly installed on the bicycle beam. An adjusting pull rope is mounted between the second connecting seat and the operating hand brake; the locking pull rope and the adjusting pull rope can be operated by operating the hand brake, the sleeve is pulled by the adjusting pull rope to rotate with the pin shaft as the center while meshing of the locking pin and the gear is released, and therefore the inclination angle of the steering main pin is adjusted, the purpose of adjusting the caster angle of the steering main pin is achieved, and different road condition requirements are met.

Description

technical field [0001] The invention relates to a three-wheel cleaning vehicle, in particular to a manpower three-wheel cleaning vehicle with adjustable caster angle. Background technique [0002] Cleaning staff often need to use manpower tricycles when cleaning the road. Manpower tricycles are very convenient to use on flat roads, and the speed is easy to control and not too fast. According to the structure of the tricycle, the angle between the steering kingpin and the vertical direction is the steering kingpin caster angle. If the steering kingpin caster angle is reduced, the steering is flexible, the riding is labor-saving, and it is suitable for uphill road conditions; If the caster angle of the steering kingpin is increased, the handlebar will be more stable, and the ride will be strenuous, suitable for downhill road conditions. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a manpower tricycle cleaning v...
